Printer profile operations

OctoPrint allows the management of Printer profiles that define a printer’s physical properties (such as print volume, whether a heated bed is available, maximum speeds on its axes etc). The data stored within these profiles is used for both slicing and gcode visualization.

Retrieve all printer profiles 

GET /api/printerprofiles

Retrieves an object representing all configured printer profiles.

Returns a 200 OK with a profile list.

Requires the CONNECTION permission.
